Electrical power grid monitoring apparatus, articles of manufacture, and methods of monitoring equipment of an electrical power grid are described. According to one aspect, an electrical power grid monitoring apparatus includes a communications interface configured to access electrical data indicative of electrical energy received at a plurality of consumer locations from an electrical power grid at a plurality of moments in time, the consumer locations being coupled with one or more unbalanced single phase feeders of a distribution system of an electrical power grid and which individually comprise a plurality of components configured to conduct the electrical energy from at least one electrical energy source to the consumer locations, and processing circuitry coupled with the communications interface and configured to use the electrical data to estimate a state of the electrical power grid and to identify one of the components as being in a potentially degraded state using the estimation of the state of the electrical power grid.
